Application filed October 18, 1915. Serial No. 56,472.

To all whom it may concern: 7

Be it known that I, ALFRED L. Panirnnmi, a citizen of the United States of America, residing at Lambertville, Monroe county, .h'fichigan, have invented new and useful Presses, of which the following is a specification.

This invention relates to printing presses.

This invention has utility in the handling of stock, as paper, for exposing to a repetition of similar actions, as in printing upon sheet or web material.

The press comprises the main frame 1 which has an outwardly extending bracket 2 having downwardly extending therefrom the arm 3 carrying the stub shaft 4 upon which is mounted the drive wheel 5. This shaft l hasfast therewith the bevel gear 6 in mesh with the bevel gear 7 carried by the bracket 8 from the frame 1. The bevel gear 7 is in mesh with the bevel gear 9 opposing the gear 6 and loose on the shaft 10. Between the gears 6 and 9 is the splined collar 11 rockable by the bell crank 12 to clutch the gear 6 or the gear 9 for driving the shaft 10 in reverse directions. The bell crank lever 12 is carried by the bracket 13 from the frame 1. The shaft 10 has fast therewith the gear 14.

The gear let is in mesh with the idler pinion 15 disposed thereabove in the frame 1, which idler pinion 15 is in mesh with the gear 16 fast on. the shaft 17 carried by the frame 1. Also. fast on the shaft 17 is the pinion 18 in mesh with the gear 19 fast on the shaft 20 carried by the frame 1. This shaft 20 has a wabbler or angularly disposed cam 21 thereon engaging the channeled roll 22 fast on the shaft 23 which carries the upper or first roll 24 of the inking train longi tudinally oscillated by the cam 21.

lVhen it is desired to use different inks or inks of more than one color, this first roll of the inking train may have a central recessed portion 25 of an eXtent greater than the longitudinal reciprocation of this roll, thereby avoiding intermediate mingling of these different inks or colors. Two color work may be run off in this manner by hav ing the imprints double size and running the stock through twice, making, in the aggregate. one operation for each article turned out.

The ink may be supplied to this first roll 24 of the inking train by rotary reservoirs or ink supply rolls. Mounted on the frame 1 are the rocking arms 26 carrying the trunnions 27 0f the inking rolls, which accordingly may fall by gravity toward the roller 24: for frictional rotation by contact therewith.

the rollers 48, 4:9, 50.

cent each compartment aslot 35. Adjacentthe slot 35 is an opening 36 in the outside of the roll member 31. The effective size of this opening 36 may be adjusted by the spring wing 37 movable across the'opening 36 toward the slot 35 by the set screw 38 accessible through the opening 39 in the member 31.

The reservoir proper 34; may have'at' intervals therealong grooves 40 (Fig. 5) for partitions a1 (Fig. 2), thereby dividing the reservoir into a plurality of compartments. This sub-division of the reservoir will permit greater refinementsin the control of ink flow therefrom.

For eachcompartment there is a discharge assisting means comprising the compartment closure member 42 having rigidly fixed therewith the yieldable means or spring loop 13. Opposing the roll section 31' is the roll section 4% having fixed thereon a plurality of brackets 15 to abut theloops or springs 43 and thereby cause a yieldable pressure action upon the closure 12 in assisting flow of ink through the slot 35 and the opening 36 from this rotary reservoir inking roll.

To increase the compression and thereby the discharge rate for a particular region or compartment along the inking roll or ink reservoir, screws 46 may be adjusted outward to increase the compression of the springs 13.

As shown in Fig. 1 the inking reservoirs or rotary ink supply rolls may be grouped about the roll 24; and the supply may be quickly and easily reduced by merely rocking the reservoir free from contact with the roll 24:.

Fast on the shaft 17 to be rotated thereby is the inking roller 47 which is contacted by (Figs. 1, 6, 7.) Rolls 49 and 50 each have fixed therewith a chan nelcd roll 51 coacting with the cam 21 on the shaft 20. Accordingly, while roll 49 transmits its rotation from roll 47 to effect rotation of the roll 2% and the inking reservoirs coacting therewith, the rolls 2 1, 48 and 50 of the inking train have oscillation or reciprocation, the former as to the inking reservoir rolls and roll 19 and the latter as to the roll 47. The reciprocated rolls are each actuated by the cam 21 coacting with the channeled rolls 22 and 51.

The inking train down to and including roll 4:7 is effective (Figs. 1, 6) to thoroughly and uniformly distribute the ink and this ink from the roll 47 may be taken by the idler rolls 52, 53, respectively carried by arms 54, 55, from the shaft 10 on which the copy carrying roll 56 is fixedly mounted. Set screws 57, 58, permit adjustment of the rolls 52, 53, into such frictional contact with the roller 4E7 of the inking train and the copy carrying roll as may be desired.

The copy carrying roll 56 may to advant'agehave'copy anchoring means thereon the spiral or angularly progressing undercut ways 59. In these ways may he slipped from the end of the roll the flare nuts 60 for the screws 61 having the wedge side-blocks62movable into contacting relation with the inclined sides of the copy carrying: frame 63. \Vith these wedge blocks 62 moved in the various grooves for closely engaging position as to the frame 63, these screws 61- may be tightened for effective anchoring of the copy carrying frame 63 configured to the curvature of the copy carrying roll 56. The copy carrying frame 63 may have overhanging flanges 61 under which may engage the tongue 65 of the liners or spacers 66 (Figs. 8, 9, 10, 11) provided with interengaging means orribs 67' to coact with grooves 68 in the copy elements or type 69. These liners 66 are thicker on their upper or outer portions than at their root or base portions to care for the curvature in the frame 63 andpermit of close fitting of the copy elements as locked in the frame by the wedges 70 (Fig. 6).

Opposed to this copy carrying roll 56 isthe roll 71' (Figs. 1, 6, 13), positively driven by the gear 71. In direct printing-the'roll 71 may have a packing 72 of yieldable or fiber stock brought around under the wedge 73 having the terminal pins 7a to be engaged by the wedge hook 75- and' firmly drawn down intoanchoring position. \Vith this end of the packing 72 firmly held, the packing should loosely extend about the roll to approximately fully embrace this roll 71.

For independent removal there is mounted over this packing sheet 7 2 the draw sheet or make-ready face 76. This sheet of flexible stock which in direct printing may be of Manila paper, while in offset printing it is preferably a rubber, may have an end thereof inserted between the members 77 and 78 of the clamp (Fig. normally held in assembled relation by the spring clip 79. Vith the strip 76 inserted between these clamps 77, 78, the pins 80 may be forced through this sheet 76 to additionally assist the opposing aws of the-clamp member 7 7, 73in firmly anchoring one end ofthe sheet 76.. The other end of this sheet may be wrapped about the face of the sheet packing 72 and brought under the wedge block 81 mounted'for swinging out of position onthe links 82. This wedge block 81 has terminal pins 83 which may be engaged by the lock- \Vith additional sets of clamps 77, 78,

when. the sheet 76 is a make-ready sheet, any

- special copy can be built up for use and the sheet 76 removed with its clamp, the copy taken off and other copy used. For re-use of the first copy, itis not necessary to again build up the make-ready for it may be brought back and placed identically with its original position without any delay and copy run off at once.

In offset operation. say when the roller 71 has a soft fiber or rubber jacket for the draw sheet, to take ink supplied from the outstanding copy on roll 56, this offset may be transferred to stock passing between the roll 71 and the lower roll 90, which in this operation has its gear wheel 91 in mesh with the gear wheel 71. This roll 90 and gear 91 are mounted on the shaft 92 carried by lever 93 from the frame 1. In order that stock may be fed through the press in the same direction for offset work as for direct printing, the lifting of the gear 91 into mesh with the gear 71 acts upon the link 94 and rocks the bell crank lever 12 to reverse the direction of the driving train by throwing the clutch 11 from the gear wheel 6 into mesh with the gear wheel 9.

For supplying the stock to the press there may be an intermittent feed device for the material. As shown in Figs. 6 and 13, this may comprise a cam 95 fast on the shaft 10 which may be engaged by a. pin 96 on the lever 97 having its fulcrum 98 fixed with the frame 1. Upon rotation of the shaft 10, this lever 97 is oscillated. This lever 97 is adjustably connected by the set screw 99 to the rod 100 to effect vertical reciprocation of this rod. To the lower end of this rod 100 (Fig. 14) is connected the bell crank 101, 102. pivotally mounted at its angle upon the shaft 103 which has fixed thereon the fourtoothed wheel 101. This shaft 103 is mounted in the bracket 1.05, which bracket 105 carries the gravity pawl 106 confining the rotation of the shaft 103 to clockwise rotation by engaging the teeth of the member 104. As the rod 100 descends, the dog 106 thereon held in engaging position by the weight 107 engages a tooth of the member 101 and pushes downwardly for a 90 rotation with the shaft 103. In this downward travel the dog 108 normally held by its counterweight 109 to prevent back-lash of the shaft 103 is carried by the arm 102 to have the counterweight 109 ride along the cam 110, thereby throwing the dog 108 free of the toothed member 104:, so that, as the rod 100 completes its downward travel and starts upward, the dog 108 may clear one tooth of the member 104 and ride up against the next tooth of the member 1041. This intermittent rotation of the shaft 103 (Fig. 13) drives the gear wheel 111 and the pinion 112 meshing therewith for 180 rotation of the shaft 113.

Adjustably mounted along the shaft 113 by set screws 111 may be the collars 116 carrying opposing are members 117 (Fig. 15). Each of the are members 117 on its after side carries a pivoted dog 118 normally held in thrown position by the spring 119. Accordingly, in the 180 rotation of the shaft 113 the friction face segment 117 coacting with the loose roll 120 on the shaft 103 will force a length of stock thereover to pass over the bracket 121, Fig. 16, and under the roller 122 held against the face of the roll 90 by the arm 123 fulcrumed at the pin 124 and having its arm 125 normally upwardly urged by the spring 126, the force of which may be adjusted by the nut 127 on the pin 128.

In the event the stock is sheet material, after the feeding of the length past the intermittent driving device, the spring 119 on the lower dog 118 will throw this dog into intercepting position so that the next sheet passing over the roller 120 is stopped in a definite position for a repetition of this feeding operation.

This feeding operation may occur from a table 129 upon which the brackets 105 are mounted. This table may be movable into different feeding relation positions so that stock may be fed therefrom between the rolls 56, 71, as shown in Fig. 1, or between the rolls 71, 90, as shown in Fig. 13. To permit of this adjustment of the table 129, it is carried by links 130, 131. The links 131 are provided with lugs 132 normally in up standing position anchored between the opposing cheeks 133.

For turning the table into lowered position the set screw 99 on the rod 100 is released. The table 129 at its outer end is lifted to bring the lugs 132 clear of the cheeks 133 and the table then swung outward from the press and downward on the pins 134 and 135. As the table gets into lowermost position, the eccentric 136 on the pin 135 lifts the link 137 and through the pin 138 and slot 139 permits the spring 1 10 to actuate the lever 93 upward to bring the gear 91 into mesh with the gear 71 as well as bring the roll 90 into position for passing stock therethrough for receiving ofl'set impression from the roll 71.

In the normal operation of the press, the

treadle 111 may be operated to actuate the link 112 which has a collar 11-3 to engage the lever 93 and a loose pin 1% to engage the lever (Fig. 1.) In offset printing operation, this pressing down of the treadle 111 will throw the rolls 90, 71, sufliciently far apart, owing to the early engagement of the collar 1&3 with the lever 93, to permit removal of stock from between said rolls. This movement is permitted by the slot 139. The shifting of the shaft 92 carrying the roll 90 is suflicient to act through the link 5H and bell crank 12 to throw the clutch 11 into disconnecting driving position.

Similarly, when the table 129 is in upper position and the press being run for direct printing. actuation of the throwoff treadle 1+1v downward will cause the pin list to pull the roll '71 suliiciently far from the copy carrying roll 56 that paper stock therebetwcen may be removed.

In the operation of the machine, the rotary ink supply reservoirs may be charged by removal of the section all and ink supplied in the various compartments there along, the inking reservoir re-asseinbled by screws 1&5 and mounted in position as to the roll 2-4:. Say paper stock is being supplied over the table 129. while in the upper position, driving of the pulley 5 will occur as shown in Fig. 6 by arrow, for rotation of the inking train, reciprocation of the ink distributing rolls as well as rotation of the ink supply reservoir for the delivery of the distributed ink to the copy mounted on the copy carrying roll. Stock intermittently fed through the machine by the intermittently driven are members 117 will repeat proper delivery of the stock for successive impressions.

lVhen the copy used is designed for offset reproduction, the table 129 is shifted to lowermost position and the press automatically assembles the rolls for offset operation and reverses the drive by shifting the clutch 11 so that stock may be fed from the table 129 to the offset side of the roll 71. In a similar manner as to the feeding above, the intermittent grip device may be re-set by the set screw 99 in the lowered position.

\Vhat' is claimed and it is desired to secure by Letters Patent is:

1. A press comprislng a copy carrying roll, reversible driving means for the roll, follower rolls driven from said driving copy roll including an impression roll connected to be rotated coincidentally from the copy roll whereby register is maintained between the driver and follower rolls, and means for throwing off one of the follower rolls without stopping the drive for the copy roll.
